So here is how this is going to work. We're all going to place imaginary bets because I'd love to but shouldn't scam everyone that sends in money to me. So don't send me anything you don't want me to keep. Then, after a while, Bopp will post on the thread how she'd have made all of the gear in Spiral Knights and we'll see who was closest. When that happens I'll update the OP.
My bet, is that Bopp would make it more centralized, where class armor etc. would be accessible.
I imagine Bopp would recommend buffs for:
Both cutters, but WHB moreso
Winmillion, giving it a 5*
Status flourishes
Gran Faust, perhaps lowering charge time?
CIV
Both troikas, but Triglav moreso
Magma and Hail Driver
Magnus, both branches but Iron Slug moreso
They would not throw out much opinions about bombs, as it's not their field of expertise
I assume they would also recommend buffs for basically anything that is not black kat, chaos or class armours.
